What to submit and where to send your application
Physicians are responsible for completing the TUE form and providing the required supporting information. Applications can be completed directly in WADA's Anti-Doping Administration Management System (ADAMS) or using an electronic or paper form that is submitted to the athletes' ADO. TUEs can only be submitted to one ADO.
BADA provides a series of checklists to ensure that all supporting documentation is included in the application.
National-level athletes must apply to the National Anti-Doping Organization (NADA). International-level athletes must apply apply to their International Federation (IF)
ADOs decide how they define what a National-level or International-level athlete is. Athletes should verify with their ADO before applying for a TUE.
